ActionScript 2.0 :: Storing Tree Component Contents In Database
Aug 4, 2006
I've got a tree component on the stage that the user can add folders and questions to. I need to write the data from the tree into a database as the user adds items and then re-build the tree from the database when the user re-opens the program. This works fine except the client wants the user to be able to delete and move items within the tree.
I'm not sure how I can track the position of items within the tree so that it re-builds the tree (from the database values) in the same order as it was when the user closed the program?
At first, I thought I would just add the getDisplayIndex of the selectedNode, but that changes when you expand or collapse a folder, and it would also mean that I would have to update a number in each database entry any time the user moves a folder or item...
I'm thinking the only way I can get around this and ensure the db tracks the latest treeview is to provide a "Save" button and make the user hit that (instead of hitting the "Accept Changes" button which currently exists for each item & folder and just updates the database on each new entry). With the "Save" button, I could just copy a new database on top of the old one (removing all the unique id indexes) and then write to the new db. Not the end of the world, but it seems more ponderous and less intuitive. Plus, if the user enters hundreds of items, it could take time to write the entire db each time...
I have an accordion component that contains 3 list components and 2 tree components...there are all the components from the flash library of components...and I need to print the contents of these 5 "lists"For now I'm concentrating on the lists...then I will worry about how to print the trees with all the nodes expanded...but I can't seem to figure out how to determine how many items are in a list.
I want to store a filesystem tree into MongoDB within a Ruby application, so we are talking about json/bson representation of something like:
/ /foo /foo/one /foo/bar/two /foo/bar/three /four
my aim is to store it efficiently and to serve it via json to an Adobe Flex application which will display it in a Tree component. which is the best solution in your opinion? this document suggests some options. i'd like to go for something like the first pattern (keeping in mind the limit of 16Mb document size) with this format:
I am creating a flex collection in which as model I have an array collection of slides.Each of the slide has a set of objects like array of images , array of captions etc . I want to pass these slides to the web service coded using asp.net and C# , from where it will be saved to a sql server db. Is there a way to send the image Array directly to the web service or I have to send each of the image separately by making as many calls to the web service as the number of images in the array .
In general what would be the most efficient way to send these array of slides and the associated objects to the web service so that they could be stored in the database ?
I'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?
I have an xml file it's structure like down below :
[Code]...
I looked for couple of examples It uses Xml attributes to shows as tree components' labels. But I want to show these xml text contents in tree component. But i couldn't find an example how to show as label these xml text contents.
Is there any way to put scroll of tree component in left side of component or creating a custom scrollbar for tree component i asked in many forums but i think all flash designers are dead
My cfm script pulls the contents of database fine. (a cfoutput reveals variables). In flash however I cannot see my dynamic variables.
// In the flash mainframe I have. loadVariables("LoadVars.cfm",0,"GET"); // I've also tried this: myLoadVars = new LoadVars(); myLoadVars.load("LoadVars.cfm"); // In the LoadVars.cfm I have. <CFQUERY NAME="ElfVars" DATASOURCE="ElfQuest"> SELECT * FROM Stats </CFQUERY>
I have a dynamic text field named "Name". Why doesn't it display the Name in the database. I can see my variable hardcoding cfoutput in the page. SQL is working. Why can't I see them in Flash?
In my main .fla file I have a movie clip onstage called "square". The movieclip is empty. Below that are five buttons (black, red, blue, green, remove) which, depending on the color button clicked, would load into the empty "square" clip either a movie called "black_square.swf", "red_square.swf", "blue_square.swf" or "green_square.swf". Only one such movie at a time is loaded into the clip. Clicking the "remove" button empties the clip. I've also got a "submit" button, which, when I click it, I'd want to submit the name of whatever .swf file happens to be loaded to a database. If nothing is loaded I want the record created to show the "square" movieclip was empty.
I've been able to make an application that has a central movie clip containing 20-something other clips. The application lets people create their own design of a particular item, choosing the colors of every component to this item (each of which is loaded into its own component-specific movie clip). One of the movie clips can be populated by a .jpg or .png file a user himself uploads. Once finished, people can print or save this design by choosing the appropriate button on this app. What I'm trying to do is find a way to also pass this design, created from multiple movie clips into a central clip, into a database as well.
The movie clips are "driven" by 21 color chip buttons each which has an instance name of a color, i.e. "black", "brown", "dark_green", etc. By a series of switch/case statements, when one clicks a "component" button (there are approximately 13-15 components) they load into the clips a movie named "(model)_(view)_(component)_(color (event.target.name)).swf". There are many "models" to choose from but within the stage only one "model" is selected at a time, so that wouldn't change here.
The design can be viewed from front, back, left or right, so that's what the "view" is - the colored components that are the same save for the view (i.e., an object which can be seen from either the front or left view) are loaded into movie clips that are either visible or invisible depending on which view one selects. Is there a way I can attach a variable name to a movie clip which is selected (bearing in mind that the application viewer can change the color of each component (and therefore the clip loaded) at will) to be read by the database? Or would the name of whatever movie clip itself that happens to be loaded be sufficient? "populating a database from contents of a movie clip".
I'm trying to use the tree component in conjunction with a php page I have that produces xml. But I am literally struggling so much its ridiculous*. My php page is printing out this:
I have created a tree diagram using the 'Tree Component' in flash, and have linked it to my XML file: <?xml version="1.0" encoding="iso-8859-1"?> <node label = "Sports Club"> <node label = "Ball Games"> <node label = "Tennis" /> <node label = "Soccer"/> <node label = "Bassball"/> [Code] .....
If you haven't noticed yet, the tree diagram is nothing complicated, it branches out as 'ball games' and 'athletic games' with sub categories such as tennis, soccer etc. (or 100 Meter & Hurdles for Athletic sports.) Now I've managed to go this far, BUT, what i'm trying to do is that when the user chooses the subcategory e.g. 'Tennis' from the tree diagram, I need to get text into a blank text-box.
I was wondering if I can change the font style, weight, color, etc of an individual node within MM's tree component. I know you can use setStyle to change all elements, but I want to try to narrow it down to certain nodes. Also on a side note I was wondering if the tree component will render text as html.I am loading the content from an xml file.I was wondering if there is a way to have some of the nodes in the document render bold in the tree component.
Edit: I have found more info on what I would like to do and it involves the use of the CellRenderer API.
get the mousewheel working with my tree component? I have this code - but it doesn't seem to work. hmmmm [AS]var mouseListener:Object = new Object(); mouseListener.onMouseWheel = function(delta) { trace(delta); trace('hello'); } Mouse.addListener(mouseListener);[/AS]
I'm using the tree component for a little Windows Parody I'm making. In my .fla, There's a tree component that loads an external XML file. I can't figure out how to add custom icons to my component, though.I know it's possible to set the icons for just the default folder and file icons, but since it's a Windows Parody, there'll be different icons for different file types, folder types, etc.In other words, I'd like to have a different icon for every item in my Tree component.
Also, I don't need to have an XML file loaded. If there's an easy way that does it all within Flash, please tell me. I just need to be able to handle events from the Tree.
I have created a MyTreeItemrenderer extending TreeItemrenderer.
However, I do not want any label, folder, disclosure icon nor icon. I want to dispaly every node of the tree with my own graphic like eg: a line, round image etc.,
now, i have a labelFunction that passes in the xml..as an object but when i ran the programme, the tree view has each node, name, num_vars and variable as branches but the content in each of them was null and blank.
how can i properly display the namespaced XML on a tree view such that it shows every branches and elements in each branch?
private function treeLabel(item:Object):String{ var label:String = item.localName(); return label; }
got a client that wants an app that will allow users to build something almost identical to an organization chart, dragging information blocks (tree nodes) and attaching them to higher tiered nodes (which are themselves info blocks) and rearranging branches as required. The client doesn have nearly enough budget for us to construct the chart component from scratch so hoping to find a readymade AS3 component that will work with some tweeks
How do I indicate the visit history on a flex tree component? I want to highlight the clicked/visited nodes to a different color and will not change after that, so that all the visited nodes will be one color. I tried adding an attribute to the underlying XML by
[Code]....
This code does retain the new color, but it also changes the color of nodes which are not visited at all. What am I doing wrong here? Is there any better way to achieve this?
Is there a way display the display list in the Tree component. I could parse the display list into xml but then I would not be able to create a reference to the display object.
